Naming Ionic Compounds – Answer Key Give the name and molar mass of the following ionic compounds: Name 1) Na 2 CO 3 sodium carbonate 2) NaOH sodium hydroxide 3) MgBr 2 magnesium bromide 4) KCl potassium chloride 5) FeCl 2 iron (II) chloride 6) FeCl 3 iron (III) chloride 7) Zn(OH) 2 zinc hydroxide 8) Be 2 SO 4 beryllium sulfate 9) CrF 2 It is often described as Na + salt of the P 3− anion. Formula For Sodium Phosphide. Na 3 P is a source of the highly reactive phosphide anion. Phosphine is a colorless, flammable, explosive, and toxic gas. Metal phosphides are hydrolysed to phosphine upon contact with water or stomach acid. Sodium phosphide is the inorganic compound with the formula Na 3 P. It is a black solid. 6 years ago. Nickel (II) iodide Ni 2+ 10. Silver sulfide Ag + S 2-Ag 2 S 3. Sodium phosphide is the inorganic compound with the formula Na 3 P. It is a black solid. It is a black solid. In order for these two polyatomic ions to bond the charges must be equal and opposite. 19) magnesium acetate Mg(C2H3O2)2. Once the sodium has donated an electron though it gets a bit clingy and sticks to the phosphorus "ohh I love your electronegativity let's go steady, text me!" sodium sulfur ? Freeman, and W.D. When Na3P is removed from the ternary catalyst polymerization of propylene and 4-methyl-1-pentene is not effective. This section provides a listing of alternate names for this chemical, Binary phosphides include phosphorus and one other element. The names are found by finding the intersection between the . Sodium phosphide, Na 3 P, is a black, ionic salt containing the alkali metal sodium and the phosphide anion. It is used as a reagent in the production of other chemicals and as a catalyst in the formation of polymers. In addition to Na 3 P, five other binary compositions of sodium and phosphorus are known: NaP, Na 3 P 7, Na 3 P 11, NaP 7, and NaP 15. USA.gov. Sodium phosphide - Na3P is an ionic compound as it is a metal. Sodium Phosphide c. Sodium Phosphate b. In its anhydrous form, it appears as is a white, odourless powder.
